Working principle and technology: the use of piezoelectric inkjet technology, the nozzle according to the curvature of the bottle and the diameter of the automatic adjustment of the inkjet, with UV curing technology, instantaneous curing ink, to ensure that the color is long-lasting, to improve production efficiency. Equipment type and applicable scenarios: Printing size, desktop small printers are suitable for small batch, small bottle printing, large industrial equipment to meet the needs of large-scale production; functionality, ordinary type to meet the regular printing, add white ink, varnish printing function models, can enrich the bottle effect. Application advantages: printing accuracy up to 1440dpi, support for personalized customization, glass, metal and other materials can be adapted to a variety of cylindrical bottles, and the use of UV curing ink environmentally friendly and emission-free. Daily maintenance: printheads need to be cleaned daily with a special cleaning solution, proper management of ink, regular lubrication of mechanical parts, check the belt tightness.
